Where was the singing coming from? I heard it blocks away and finally saw the members of the Pentacostal Roca de Seguridad out on the sidewalk. Their building was put on the market a few years ago, but it looked like the church had managed to keep it. I swung back to the corner half an hour later to see if I could take a picture or two up close, only to find it empty. I'd missed at least a couple of opportunities.
